"I was recommended to go to Preto because my teenagers would love it. The menu is very simple, everything is included in the grill, and we were offered delicious sides and desserts (although a bit rich for my taste). We used a voucher code which made the meal very reasonable, but I was not made aware (and didn't notice) the discretionary 12.5% added to the bill. I appreciate the hard work of the staff, who make the restaurant welcoming. The space was largely empty and not very cozy, but it seemed a bit unfair not to have been informed about the discretionary charge. Other restaurants usually add the charge at the point of paying for the food, with your consent. This left a negative impression after what was otherwise a very tasty meal."
